Chapter 17: The Reason Of Coming Here

They had inform soon the battle is over and everyone are safe, even Ieyuji. Timoteo is glad to hear the news and much more when he met Ieyuji. Timoteo hug Ieyuji, telling him how happy he is to see him alive and safe but for Ieyuji... deep within, he was bothered by something. In his eyes, there was a reflection of pain and regrets.

Reborn asked Dino to accompany 9th to the Vongola's rest house which is near somewhere in Namimori. Dino would gladly comply with it. Timoteo thank Tsuna in his hard work and gave an apology that he can't help on the scenario.

"Don't worry Grampa, as long as you're safe, that's fine by me." Tsuna answered with a smile.

Soon, they all went their ways. Mukuro asked both Ken and Chikusa to rest and they can have a nice reunion in the afternoon. Tsuna, his's Guardians, Reborn, Ieyuji and I-pin were now walking on Sawada's home. They all found it quiet. Ieyuji was looking away to his brother's eyes, not even glancing, nothing. Tsuna was worried for him. Little did they know, they finally arrived.

They all stop, like they were thinking if they should go in or not. Knowing how they feel, Ieyuji was the first one to open the door and went in. They all soon followed.

Ieyuji was only thinking about heading to his room but unable they know, someone was actually waiting for them.

"Yuji-kun"

Ieyuji stopped and looked on the dining room and surprised, Nana, their mother was awake with Bianchi.

Gokudera and Yamamoto greeted "G-good evening"

"I'll say morning. Look at the time it's already 3am in the morning. I'm always worried you know, for this past weeks." Nana told them, not really liking how they keep secret from her.

Gokudera bowed down to her "I'm very sorry Sawada-san but we promise that's the last." He stood up straight "We finally done from our goal."

"Goal?" Nana questioned.

Bianchi stood up from her sits. Reborn went on the top on the table and looked on the scene. Yamamoto and Gokudera smiled and went to the side to give ways. That's when Tsuna came out.

Nana was shocked, she can see his brown eyes and smiling and what's more when Tsuna spoke to her.

"I'm home... Kaasan" Tsuna said smiling.

Nana can't believe it. Her tears came out to her eyes and immediately hug her son. So happy to see his honey eyes, his voice and his smile. Tsuna hesitate at first but then he returned her hug.

Mukuro and Chrome came out beside the table to have a greater view on the scene. Ryohei was just behind Tsuna, Lambo and I-pin were just beside Ryohei and Hibari is in the front door. They were all happy for their sky, that finally, they had cured him.

Tsuna pulled her away for a bit and his smile turn into a sad one. "Kaasan... there is something important you should know."

"Tsu-kun?" Nana questioned but still tears coming down. Tsuna turned to Ieyuji who was still looking away "You too... Ieyuji."

Ieyuji flinch for a bit but then nod. Tsuna looked to Reborn, somehow telling him something which Reborn understood and nod.

"Bianchi take I-pin with you and go to bed, these are all just between us." Reborn told her.

Bianchi was surprised at first but then nod.

'Good, I can't handle Aniki for less than an hour' Gokudera thought, he can feel his stomach growling in pain for a bit as he think about her.

Soon, they were all in the dining room and Hibari was far from them. Nana sat on the opposite side of Tsuna. Ieyuji was just standing, not liking to sit at all. Lambo was being carried by Chrome and Reborn just sat on Yamamoto's shoulder which is he is standing on Tsuna's left with Gokudera on his right side. Everyone is quiet until Tsuna spoke.

"I have wanted to tell you to tell you this for so long because... you need to learn the truth."

"What is it?" Nana asked.

Tsuna took a deep breath before saying "I'm not your child." Nana was shocked and so is Ieyuji who immediately looked at him in wide eyes. Tsuna continued "Your true son, Sawada Tsunayoshi is already dead."

"Wha-what are you talking about Tsu-kun?" Nana asked, confuse at the same time, shock.

"As I had said, he died on the day he was stab. I too am Sawada Tsunayoshi but not your son, I came from another parallel world." Tsuna explained which Nana found it confusing even more.

"He-hey, just what do you mean from that?" this time, Ieyuji asked.

Tsuna turned to him and answered, "I'm from the different world, all of us do... and also from the future." He turned to Nana, "Ka-, no, Nana-san I will tell you straight. This body is actually from your Tsunayoshi, your son but this soul inside is different. It is from another world."

Gokudera continued "How we got here is something we don't know after we died on our world but somehow, we had awaken ourselves here in this world, occupying the dead bodies of ourselves from this world."

"In summary, I am not your son from the inside Nana-san." Tsuna said with a sad smile.

Nana can't believe on what she was hearing, even Ieyuji.

'Does that mean he really died? I really lose my twin brother and this person... is not my brother!?' Ieyuji thought to himself.

Tsuna who can see their shock and confuse closed his eyes, waiting for them to recover a bit.

Nana faced him and asked, "When did you arrive?" Tsuna opened his eyes and answered her, "On the day on the hospital, it seems on where you were there crying on my alternate self's death with Ieyuji."

"So... it wasn't a miracle then..." Nana cried, unable to hold back the pain after hearing the truth. Her son is dead, her real son is dead.

"I also inherit my alternate self's memories, so I knew everything until his last moment." Tsuna added.

Nana looked at him and asked "Then tell me, how did my Tsu-kun died?"

Ieyuji had his eyes widen, there is fear, and he is shaking which everyone except Nana notice.

Tsuna took a deep breath and asked first "Are you sure? The truth is painful and also... we had already destroyed the killer so I think there is no need to know."

"Destroyed?" Mukuro questioned in low voice but then think '... Could it be...'

Nana gave him her determination to know the truth "Tell me"

Tsuna stayed quiet, observing her thoroughly and then looked to Ieyuji who was shaking in fear.

"Ieyuji" Tsuna called out which startled Ieyuji. He slowly looked at him and surprised he has a small smile to him and it was also a reassurance smile, "It is not your fault, I will reveal it to you. It is not your fault."

Ieyuji doesn't understand, it was obvious it was his fault and-

"Mukuro can you help me out?" Tsuna asked him with a small smile. Mukuro chuckle on his request, "Kufufufu of course Tsunayoshi."

Mukuro went beside him and offer his hand to him. Tsuna gladly accepted his hand and the place soon change, like they are all being warp to another place.

"Wha-what's going on?" Nana asked in bit panic. Ryohei went beside her, "Don't panic Nana-san, just wait and see."

Nana found it questioning until the place turn dark. There was no light at all and no one was around.

"What just... !" Nana was shocked to see the young Tsuna came.

He seems heading to the kitchen and did. He went to the refrigerator to get some cold milk and went to the sink with the milk to get a glass. They all keep watching until someone came. They all turn around and it was the younger version of Ieyuji.

"Yuji-kun?" Nana questioned. Ieyuji on the other hand wanted to run away but was stopped by Hibari who was on the way.

"Don't run and see the truth Herbivore." Hibari told to Ieyuji.

Ieyuji looked back on the scene.

The younger version of Tsuna asked "What's wrong Yuji-kun? Do you want some milk too?" he said with a smile.

The younger version Ieyuji was looking down, unable to see his eyes. That's when they saw his evil grin which somehow alarms them. They were all surprised when they heard him speak.

"Die, you should die and disappear" The younger version Ieyuji said but something was not right. His voice is not his voice, it was someone's voice.

The younger version Tsuna was alarm in fear, knowing something off about his younger brother.

"W-who are you? What have you done to my younger brother!?" younger version Tsuna shouted. Even he was shaking in fear, he was trying to be courageous in front of him.

'That voice... that's!!' Reborn realized it.

The younger Ieyuji was laughing like a demon which made Nana, younger version Tsuna, Ieyuji and Lambo shake. The younger version Ieyuji slowly raises his head, seeing the glowing red eyes, like the Eclipse flame.

"Die" younger version Ieyuji showed his hands gloves and knife in hand which made the younger version Tsuna scared.

The younger version Ieyuji automatically runs, heading to him.

"NO!" Nana shouted as trying to protect him but was just pass through her, like she was a ghost which made her eyes go in fear and turn around.

Everyone saw the young Tsuna grab the blade before being stab. He was fighting against him, even if his hands were already bleeding. The young Ieyuji was laughing crazy as he pushed it even more which surprised the young Tsuna. He keeps holding on, not letting him stab him.

"Yuji-kun open your eyes, Yuji-kun, YUJI-KUN!" the younger version Tsuna plead, trying to return him back.

The younger version Ieyuji was still laughing crazy as he keep pushing even more.

"Die, you must die die DIE! Disappear!"

He pushed even more which makes the young Tsuna feel even more pain to his hands, his bleeding too much as well. He then pushed his blade away and tried to run away but he fall due to the young Ieyuji caught his feet. He quickly went on the top and stabs him but the younger Tsuna grab the handle this time, pushing it away from him.

"Disappear, Die BEGAN!" The younger Ieyuji growled as Eclipse flame soon coming out to his body.

The young Tsuna can't believe what he was seeing and his strength got even more as he was being pushed to him. It was getting to him. Tsuna keep on pushing it away, still trying to fight back.

"YUJI-KUN! Snap out of it! Please! Return... RETURN MY BROTHER BACK! YUJI-KUN!" the younger version Tsuna shouted in all his heart and determination which shocked the current Ieyuji. He continued "Come back, you can fight it Yuji-kun. You are stronger than this, you're better than this, Yuji-kun!"

The younger version Ieyuji was laughing crazy and said to him "Too late, you will die and he'll be a great vessel to US! Began human!"

"NO! I will not let you take him! I... !" The younger version Tsuna was unable to finish as he was finally been stab by him, by the possessed Eclipse Flame Ieyuji.

The younger version Tsuna's tears come out. He failed, he can't save his younger brother, his beloved twin brother.

The younger version Ieyuji pull out the knife inside him, making the young Tsuna shout in pain. He stood up and now laughing even more insane. He looked back on the ground again, hold the knife in two hands, ready to stab him once again.

The young Tsuna knew it and gave a final moment of smile.

"I'm sorry I'm not strong enough to save you Yuji-kun" the young Tsuna said as tears keep falling to his eyes.

Ieyuji's eyes were becoming more in fear of horror. He can't take it anymore and shouted as heading to his brother's side

"TSU-KUN!!" Ieyuji shouted as he tried to reach him but too late.

The young version Ieyuji stabs his heart, giving him an instant death. The young Tsuna's eyes widen for a bit before closing his eyes and died.

The place returns back to normal. Ieyuji was crying, he keeps punching the ground, thinking he was the one who killed his brother. He was a murderer, a monster!

Tsunayoshi who can see the way he thinks quickly went to Ieyuji and hug him.

"Don't even say it's your fault, especially a murderer Ieyuji. You are not a murderer, it was the Eclipse flame that was controlling you ever since. It is not your fault." Tsuna told him in hard tone, serious and threatening tone.

Ieyuji was surprised on the sudden change of tone but still continued to cry. "But I... I... in my hands... I..."

"Your brother's last thought before he died," Tsuna suddenly said which surprised Ieyuji. He then told him "... 'Someone please save my brother, I love my brother, someone save him'... it was his last thought and wish. I did it for him."

Ieyuji keeps crying and asked him "Why? ... Why does he care for me even if he is already on that kind of situation? ... Why can't he just... mind himself?"

"Because he loves you, even if he suffers because of you. He knew your reason Ieyuji, he knew your plan and he was kept trying but he failed. Every time he fails, do you know what he was thinking?" Tsuna asked, making Ieyuji looked up to him to hear the answer. "... 'I'm weak and I know that but that is fine, as long as he is happy and strong, I'm happy. You are his beloved twin brother.' My alternate self was really strong when comes to will and mental strength. Maybe you failed to see that thing from him." Tsuna smiled to him.

Ieyuji after hearing that cried even more, he can't hold the pain. He suffers and regrets it. Nana who can see Ieyuji's pain makes her cry even more. She was still confuse on what kind of thing that seems possess him but one thing is for sure that it made his son suffer without her knowing. She feels like she failed them as a mother.

Reborn can see the scenario in front of him and sigh then smiled. He remembered the day on the Mist battle, he heard Ieyuji was denying the reason of his real brother's death which surprised him. Now everything is understandable. Yes, it's him but it was the Eclipse flame is the right to blame. It took over him and kills his brother to give him more suffering and hide the truth of his real feelings to his twin brother.

"I'm glad everything is settled" Reborn said which Yamamoto agrees as he smiled bigly.

Gokudera also smiled, Chrome and Lambo went to Nana and comfort her, Ryohei was smiling and so is Mukuro. Hibari also gave a small smile, it was touching for him, even if he doesn't want to admit it.

Soon enough, Nana asked them about the thing that possessed his Yuji-kun.

"Are you sure you want to know? You might regret it and it might take long as well." Tsuna said but Nana was persistent. "Tell me."

Tsuna observed her for a moment then everyone, silently asking them if he should. Looking at them, some nod, some were also unsure. He then gazed to Reborn.

"Reborn, should I tell her? If I should, I need to tell her everything, including that stuff." Tsuna told him. Reborn think for a moment before asking first, "Your mother in your world, did she knew about that?"

Tsuna smiled and nod. "My mother, Nana-san's alternate self learned it after being kept from her for so long. She able to accept it but of course she gave a hell out of Otosan. But I'm not sure from her, but I have a feeling she will accept the truth... so..."

"Then tell her, I don't mind." Reborn told him.

"Are you sure Reborn-san? I knew you were told to keep it secret from Sawada-san." Gokudera said, concern for the Sun Arcobaleno.

Reborn turned to Gokudera, "Just as you said and I was told 'I SHOULD keep it a secret', meaning I can't say any details but if other people would say it..." Reborn smirk. It means it is not one of his responsibilities.

Tsuna chuckle for a bit and Yamamoto can't help but laugh. Ryohei wanting to scream but was stop by Hibari's tonfas.

"Just like Reborn said... You know, you never change, even in my world." Tsuna commented and Reborn smiled, "Thank you."

Tsuna turned to her, "Everything I will about to tell you now is the truth."

Tsuna and the others then confess to Nana about Vongola, her husband's work, mafia, Dying Will Flame, the Ring Conflict and the Eclipse Flame. They need to tell her everything to make her fully understand on how they knew, how they fought it and why are they involve. Ieyuji joined in, telling her everything as well, including Reborn's real job from coming here, I-pin, Bianchi and Fuuta.

Nana can't believe on what she was hearing from them. It was overwhelming information which she can't believe it to be true. Her husband was a mafia, her son will soon become boss, Reborn and many more. She wanted to faint but something tells her not to and believes on them. In the end, she was glad to know everything.

"Thank you for telling me." Nana told to everyone.

They were all glad, that she understood and accepted them.

Mukuro went to the Arcobaleno and whisper to his ears "Tell her husband that he better prepare his life on his coming back home. If I remembered correctly, he was almost killed by Tsunayoshi's mother."

Reborn smirk, knowing what the alternate Nana would react. Maybe he'll watch the outcome.

Tsuna sigh in relief "Now everything are done, why don't you come out and tell us why you send us here Byakuran."

Byakuran came out from the outside.

"Hahahaha you knew I am here?" Byakuran ask with a great smile on his lips.

Everyone just stare at him.

"That guy is Byakuran Gesso. He is the one who sent our souls here." Chrome told to the confuse Nana and Ieyuji.

"So he's the one" Ieyuji said to his breath.

Byakuran went in the house and still munching some marshmallows.

"How are you feeling Tsunayoshi-kun? " Byakuran ask.

"Been better but when I see you it became worst." Tsuna said in deadpan expression that seems hurt Byakuran.

"That's harsh Tsunayoshi-kun... but I'm glad you're alright." Byakuran said which he truly means it. Tsuna smiled "Thanks and also for helping my friends to remember as well."

"Oh that was necessary so that was nothing, although I still don't understand why you became sealed. You were supposed to be normal like everyone else, at the same time remembered everything than them. What made things go wrong Tsunayoshi-kun? Do you know?"

They all look to Tsunayoshi who was thinking then answered, "I'm not sure to myself but I have a guess because of the Eclipse flame that killed my alternate self. When I came to this world, I caught a small particle of Eclipse Flame inside me but not harmful. It gave a seal within my communication and also restraining me from doing many things as well. I can move my body but has limits." Tsuna explained to them.

"So it was because of the Eclipse flame that you were sealed?" Reborn asked, clarifying everything. Tsuna turned to Reborn and nod, "The only way for me to destroy the seal is the power of the Vongola Ring. The Vongola Ring on this world, not from ours."

"Why is that Juudaime?" Gokudera asked. Mukuro answered, "Because our Vongola Gears were cut in power, the Trinisette, right?"

Tsuna nod once again. "How I know this stuff, well, I got the explanation from our Byakuran within my memories. Only about Vongola Gears and told me he'll do something for my Guardians which at first I don't understand but when Gokudera-kun came and told me about the beginning of gathering, I finally understand."

"I still hate the fact I owe the Pineapple Head from giving me my Buckle of Storm." Gokudera said in bit irritation tone.

"Kufufufu you were really hard to convince Octopus Head, fighting you whole night." Mukuro chuckle once again which irritate Gokudera even more.

Yes, remembering at that time, Gokudera lose to Mukuro which makes him mad but still grateful because he able to convince him to wear his Buckle which he did and remember everything.

"Now Herbivore, tell us the reason why we are here." Hibari said, eager to know the truth.

They all looked to Byakuran, waiting for answer.

"This is the third step right. The reason you all are here was because..." Byakuran trailed off but still silence on the room, waiting for him to continue and hear the answer. Byakuran became serious, "The trinisette's balance."

The Guardians became serious so is Reborn and Tsuna.

"What happened to the balance of Trinisette Byakuran?" Tsuna asked in serious mode, like he is the current boss who will never accept any false report more than anyone which made Ieyuji mentally flinch from his way of action.

Byakuran crossed his arms, "Currently the balance of Trinisette is not in good condition. Checker Face is currently handling things on his own until now but I don't know how much he can hang on to it."

Reborn remembered the Iron masked man and the reason why his body is currently in a form of a baby with the other Arcobalenos. 'Checker Face... That is his name huh.'

"For that reason I need the whole fated holders to help us return its balance, in other words you and your Vongola Ring, same for the Arcobaleno with their Paficiers." Byakuran said to them.

They all made a thought after hearing his explanation. Gokudera asked.

"Those who know its current condition are?" Byakuran answered, "Checker Face and we Gesso Famiglia who holds the Mare Ring Hayato-kun."

"How did this start?" Tsuna asked. He gave a deep thought about it before answering, "I am not sure actually Tsunayoshi-kun. Just that it started 20 years ago. My famiglia are still investigating its root but until now, all the clues we have is it has something to do with the experiment that had been running a long time ago."

"Experiment? Are you talking about human experiment?" Nana asked in horror. Byakuran gave a deep sigh before answering, "It seems it has a partial of human experiment activities too."

Hearing that made Nana almost collapse but thankfully Ryohei and Ieyuji acted and have her sit to calm herself. Tsuna looked down as he gripped his hands, can't believe what he is hearing and knowing this is indeed a serious case.

"Do you know whose famiglia are involved in these misbehavior activities?" Hibari asked in narrowed eyes, wanting nothing but destroy those people who dare do this.

"We are still investigating that Kyoya-kun, right now all we have is the information about a partial human experiment and flame which I know you already know what kind of flame I am talking about."

They all narrowed their eyes. The only one who voiced it was Yamamoto, "Eclipse Flame."

Mukuro asked in serious tone, "Does the Estrano Famiglia have something to do with this?"

"They are partly seems to be Mukuro-kun." Byakuran answered him before turning to everyone, "For that reason we need you all here to help us fix the balance of the Trinisette Tsunayoshi-kun."

"Us? Why need us? There are other people who are capable to do such job like Ieyuji here who will take the position of the Vongola, so why did you ask our Byakuran to send us here?" Tsuna questioned one of the things that bothered him the most.

"You heard me before Tsunayoshi-kun, we need the fateful holders to fix the balance." Byakuran said before opening his eyes in seriousness. "Replacement won't work, you do know how serious this case we are having. Knowing the fact that you all here died, I have no choice but to ask my parallel self to send you here. I did the preparation to fix your souls in this world while prepare for you to be sent here after your life had been fulfilled."

Tsuna thought for a moment before asking ones again, "You said we will restore the balance of the Trinisette, what about those who are responsible for this? I think it's best to investigate with you and stop those are responsible to this."

Byakuran smiled and nod, "I know what you mean there Tsunayoshi-kun but to tell the truth, neither I nor Checker Face aren't sure if they are still around."

"What do you mean?" Gokudera asked in narrowed eyes. Byakuran answered, "What I mean is when we discover them, they are all currently dead with no recognition anymore."

"No recognition?" Ieyuji asked, complete clueless but knows one thing, whatever that is it would be something he doesn't want to see. Byakuran smiled, knowing Ieyuji doesn't like to see it. "I have photos of them before we began the investigation. If you want to see let me know."

Tsuna gave a serious thought before glancing to Mukuro who chuckled from the silent question and order from his Sky and Light. "I will do as you wish Tsunayoshi."

Tsuna turned to Hibari, "Hibari-san, Gokudera-kun, Oniisan investigate this for me."

Gokudera bowed to his boss, "Understood Juudaime." Ryohei smirk, "Leave it to me Sawada." Hibari looked away but still answered, "Hn"

Tsuna turned to Byakuran, "I want to meet Checker Face tomorrow. Will you lead the way Byakuran?"

Byakuran smiled, seeing the boss mode of Sawada Tsunayoshi whom he didn't get a chance to see, how amazing if he would become a boss. "Will do Tsunayoshi-kun, I will lead the way for you."

"I'm coming with you Tsuna." They turned to Reborn who is showing how serious he currently is. Tsuna knows why he wanted to go, not only this could become the Arcobaleno's duty but also he wanted to find the truth why he was cursed and how to break them. Tsuna nodded, "Sure."

Reborn nodded as thanks.

Tsuna turned to his Rain Guardian, "Yamamoto there is something I'd like you to do with Lambo, would that be okay?"

Yamamoto grinned, "Of course Tsuna, anything you like." Lambo grin too after hearing his name. He was happy that his Tsuna-nii would ask him something and not really mind him being a child. "Leave it to me Tsuna-nii!"

Tsuna smiled to both of them before turning to his last guardian, his half Mist Guardian, Chrome. "Join with me tomorrow Chrome." She smiled and nod, "Yes Bossu."

Tsuna took a deep breath before speaking with gentle tone, "For now everyone should rest so we can start everything tomorrow."

"Hai"

Nana and Ieyuji can't help but stare at him. They were currently astonish to see him like this, looks like he being a Vongola Decimo on their time is indeed true.

"Tsu-kun" Nana called when she stood up. Everyone turned to Nana who was approaching him. Tsuna is already ready to say his good bye to his alternate mother since she already learned the truth and in order for her not to suffer from the real death of her son but what she did is unexpected to his part as she hug him, like a mother. "You're staying here... right Tsu-kun?"

Tsuna could hardly blink, does she... "Do you... want me to stay here? I'm not your son and-"

"Does that even matter Tsu-kun." Nana said with a gentle smile, "You may not be our Tsu-kun but you are still Tsu-kun and as you had said before, I am your alternate mother. That would mean you are still my son even if you're not from this world."

This widens his eyes before meeting her eyes. He smiled, unable to hold his happiness. "Thank you... Kaasan."

Nana continued to smile and nod. Ieyuji kept glancing at them before taking a deep breath, "You can stay here, and this is your home."

They all turned to Ieyuji with disbelief look. Ieyuji blushed on the astonished look and turned away. Reborn smirk as he pull his fedora, seeing he is now starting to accept him.

"Ieyuji" Tsuna whispered. Ieyuji sigh, "Call me Yuji-kun... like my older brother, Tsu-kun used to call me."

Tsuna smiled to his now truly younger brother, "I will then... Yuji-kun."

The night ended peacefully but on the next day is the beginning of their real mission. The time has come for them to fulfill their role as fated holders of Vongola Ring.

The mission to fix the balance of Trinisette.

I do not own Katekyo Hitman Reborn
